What is a rectangular prism?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape. It is also called a cuboid.
It is given that:
A rectangular prism is given,
Geometry can be defined as the branch of mathematics that is concerned with the size, shape, and orientation of two-dimensional figures.
As we know in the rectangular prism there are eight vertices and six faces.
From the figure, we can see clearly that point D is coplanar with A, B, and C.
Point D is coplanar with A, B, and, C.
Thus, point D is coplanar with A, B, and C because it is on the same plane as A, B, and C option (4) is correct.

3 2/3 x+3 1/4=6 whats the value of x
Answer:
x = 3/4
Step-by-step explanation:
Answer:
x = 3/4
Step-by-step explanation:
Find the LCD of the fractions. Multiplying the denominators 3 and 4 together, we get LCD = 12.
Rewriting the mixed numbers, we get
3 2/3 = 3 8/12 and 3 1/4 = 3 3/12
So the original equation becomes
(3 8/12)x + 3 3/12 = 6
We must now combine like terms: subtract 3 3/12 from both sides of this equation, obtaining:
(3 8/12)x = 6 - 3 3/12, or
(3 8/12)x = 2 9/12. Converting the mixed numbers into improper fractions, we get:
(44/12)x = 33/12. Multiplying both sides by 12 yields 44x = 33
and so x = 33/44 = 3/4
x = 3/4
Alternatively, convert the original mixed numbers into improper fractions right away. Then the original 3 2/3 x+3 1/4=6
becomes (11/3)x + 13/4 = 72/12, or
(44/12)x + 39/12 = 72/12
Multiplying all three terms by 12 yields:
44x + 39 = 72, which simplifies to 44x = 33, or x = 3/4

Find the missing length of the triangle. If necessary, round your answer to the nearest tenth
Answer: 26
Step-by-step explanation:
a² + b² = c² Use Pythagorean Theorem to find the missing length, a & b are the side of a right triangle, and c is the hypotenuse of the right triangle.
10² + 24² = x² In this triangle, the x was the hypotenuse, which is c, plug 10 and 24 into a and b.
100 + 576 = x²
676= x²
rewrite as
x² = 676
√x² = √676 [solve the square root from both side]
x = 26

Each car on a computer train holds 20 people. On a particular morning, 5 cars were 90% full and 3 cars were 65% full. If the people were rearranged to fill as many cars as possible, how many cars would be filled?
Answer:
7 cars
Step-by-step explanation:
The computation of the number of cars to be filled is shown below:
A car that is 90% full and the total people is 20 so 90% would be
= (.90)(20)
= 18
A car that is 65% full and the total people is 20 so 65% would be
= (.65)(20)
= 13
Now
Total number of people = (5)(18) + (3)(13).
= 129
Now the number of cars to be filled is
= 129 ÷ 20
= 6.45
= 7 cars
A cylinder has a base radius of 6 feet and a height of 12 feet. What is its volume in cubic feet, to the nearest tenths place?
Answer:
its is either 339.3 or 1357.2
Step-by-step explanation:

Given circle B below, find the value of x.
(3x + 10)
(2x - 17)
Answer: 44
Step-by-step explanation:
since the inscribed angle is half of true arc measure, (3x+10)= 2(2x-17).
when you work this out, you get 44 as x.
The value of x from the given figure is 44°. Therefore, option B is the correct answer.
What is relation between angle at the center and the angle at the circumference?The angle subtended by an arc at the center is twice the angle subtended at the circumference . More simply, the angle at the center is double the angle at the circumference.
From the given figure,
Angle at circumference is (2x-17)° and angle at center is (3x+10)°.
Now, (3x+10)°=2(2x-17)°
3x+10=4x-34
4x-3x=10+34
x=44°
Therefore, option B is the correct answer.
